Do you need a building permit in the Village of North Hills, NY?

Yes, for work that has to conform to the state Uniform Code or Energy Code. The Village of North Hills code says a building permit is required for any such work, subject to a list of exemptions, and the permit is issued by the village's code enforcement officer1. The village adopted the state code through its own local law and enforces the Energy Code as well10.

The state Uniform Code applies everywhere in New York outside New York City, and each local government administers it within its own borders11. In North Hills that local government is the village, not Nassau County and not a surrounding town. Permitted work then needs inspections, and the work has to stay accessible until the inspector accepts it5. A certificate of occupancy follows for any work done under a building permit6.

We did not read the village's list of permit exemptions, so confirm with the Building Department before skipping a permit for a small project.

Who handles building permits in North Hills, and how do you reach them?

The Village of North Hills Building Department handles building permit applications, and new applications must be submitted online through its portal8. Its phone line is (516) 627-3690, and village hall sits at One Shelter Rock Road, North Hills, NY 1157612.

Do not send a North Hills project to the Town of Hempstead building department. That office serves property under Town of Hempstead jurisdiction, and the village runs its own code enforcement10. Nassau County's own page says local building permits come from the applicable city, town or village13.

If the lot fronts a Nassau County-owned road, the county also asks you to contact the Nassau County Department of Public Works in addition to the village14.

Does North Hills have zoning, and what does it cover?

Yes. The Village of North Hills divides itself into use districts under Chapter 215 of its village code2. The published districts include several residential districts, two commercial districts and an educational training services district, with a groundwater protection overlay that applies in addition to the underlying district4.

Because zoning is local in Nassau County, no single county zoning ordinance governs the village. The county's Planning Commission reviews certain zoning actions that municipalities refer to it, and makes recommendations rather than deciding for the village15.

Minimum lot size, setbacks, minimum house size, accessory dwellings, RVs and tiny homes depend on the district, and we could not confirm those numbers. The village's zoning map is on file at the village office, so call the Building Department with the parcel's address before you plan a layout4.

How do septic and sewer permits work in North Hills?

Nassau County, not the village, regulates on-site sewage disposal. The Nassau County Department of Health approves on-site system plans and requires a SPDES permit before sanitary waste is discharged into the ground16. In parts of the county served by public sewers, residential and commercial buildings must connect to the sewer9.

For a single home that is not part of a new subdivision, or for a renovation, the county directs applicants to the local building department for septic requirements7. In North Hills that points to the village Building Department. The county Health Department itself takes plans for residential developments of 5 or more lots17.

We could not confirm whether a given North Hills parcel is on sewer or what the village requires for a septic system or private well. Ask the village Building Department first, then the county Bureau of Environmental Engineering9.

What are the Special Groundwater Protection Area rules near North Hills?

Parts of Nassau County are designated Special Groundwater Protection Areas, and the county's rules there limit new single-family development on individual sewerage systems to one dwelling unit per 40,000 square feet of net area, where the site is outside a public sewer service area and soils suit the system18. The county's ordinance names areas in the Town of North Hempstead and the Town of Oyster Bay18.

North Hills also has its own groundwater protection overlay district in its zoning code2. We did not confirm whether a specific North Hills lot falls inside a county-designated area, so ask the Nassau County Department of Health before assuming either way9.

Building a home in North Hills: the steps, in order

  1. Call the village Building Department at (516) 627-3690 with the parcel address to confirm the zoning district, the overlay and any exemptions12.
  2. Ask the Department of Health whether the parcel is on public sewer or needs an on-site system, and what approval applies9.
  3. Submit the building permit application online through the village portal8.
  4. Keep work accessible and call for each required inspection5.
  5. Obtain the certificate of occupancy before using the building6.

What stays with Nassau County, and what to check before you buy in North Hills?

Septic and sewer approvals, county road work and subdivision health review stay with Nassau County agencies, not the village314. For land outside the village, see the Nassau County page.

Cost context is county-level: Nassau County's typical home value is $859,54419 and its effective property tax rate is 1.5%20. Ask the Building Department about architectural review, since the village has an architectural review board, and confirm sewer service and the groundwater overlay before closing.

Watch-outs

  • The county's septic guidance sends single homes and renovations to the local building department, so a North Hills buyer needs the village Building Department's answer before relying on any septic assumption7.
  • Permits exempted from the village building permit requirement are listed in the village code but we did not confirm them; do not assume a small project is exempt1.
  • Many search results for building permits in Nassau County lead to the Town of Hempstead; North Hills is a village with its own Building Department and online portal8.
